cant stop the player with react router

[waltershub]

I am using react router and when I navigate back the audio keep playing
I tried this in the
stopPlaying() {
ReactDOM.findDOMNode(this.state.autoplayref).dispatchEvent(new Event('pause'));
}
and then
componentWillUnmount() {
this.props.shuirimprops.stopPlaying();
}

but not working. I am doing the same thing for playing and pausing and it works fine I think the
ref is alread gone by the time the async method excutes
